Method of providing element dossiers that include elements from nonadjacent lifecycle phases

ABSTRACT

Providing element dossiers may include obtaining records of relationships between elements from all lifecycle phases of interest, and querying and retrieving a list of all elements related to a target element using the relationship records including relationships between intermediary adjacent lifecycle phases. The method also includes determining inferential and correlation based relationships among dynamically changing elements.

BACKGROUND

The present disclosure generally relates to method of providing element dossiers that include elements from nonadjacent lifecycle phases.

For a given element or artifact in a given lifecycle phase one can obtain a list of those elements in the same phase that are related. For example, for a given code element, one can retrieve the code it calls, or even the code that calls it (e.g., using IBM's Websphere Studio Application Developer (WSAD) Integrated Development Environment (IDE)). One can also retrieve related elements from adjacent lifecycle phases, e.g., for a given hardware element, like a computer chip, one can obtain the designs upon which it was based, or the product which contain instances of it. However, it is not so easy to answer queries which involve elements of nonadjacent lifecycle phases or obtain a complete description of a given element, which contains data from nonadjacent lifecycle phases, e.g., earlier and/or later. For example, information for a particular piece of code such as, the (earlier) requirements which led to it, or all the (later) bug reports it caused, not only a list of all such earlier and later elements, but also the string of relationships linking them to initial target element, are not readily available or obtainable.

BRIEF SUMMARY

A system and method for providing elements dossiers are provided. The system, in one aspect, may include one or more memories and one or more life cycle records in the one or more memories, each life cycle record describing a life cycle in a work project. The system may also include one or more artifact description records in the one or more memories, each artifact description record describing an artifact in the life cycle, at least one of the artifacts being a dynamic artifact. The system may farther include one or more relationship records in the one or more memories. Each relationship record may be associated with a relationship between at least two of the artifacts and at least one of the relationship records describes a dynamic relationship. An inference engine determines a dossier that includes one or more relationships associated with a target artifact and all of the relationships associated with one or more other artifacts that have a common path of relationships with the target artifact.

DETAILED DESCRIPTION

A system and method of the present disclosure in one embodiment returns a list of elements related to a given target element. These retrieved elements that are related to a given target element may be those from lifecycle phases that are not adjacent to the target element. The list of related elements may be formatted as one or more reports in one embodiment. Data associated with the retrieved elements may be also retrieved and provided. The retrieved data may include, but not limited to, a description of the interrelationships between all of the retrieved or returned elements. The retrieved data may also include indication of whether any given returned elements preceded or followed the target element chronologically. Relationships or interrelationships may include an indication or a degree of “sureness,” e.g., absolutely connected, possible connected or were once connected.

A dossier is a specific “view” on an ongoing project, people, process, and/or others, customized for a particular person in a particular role for a particular purpose. A dossier may be a live, evolving, adaptive collection of gathered and synthesized information regarding an area of concern, for instance, based on one or more evolving lifecycle slices. Lifecycle slices may be created based on three basic kinds of information: definite, physical relationships among entities; inferred, probabilistic relationships, determined by inspection of entities; synthesized relationships, based on observed correlations over time.

In a simple example dossier scenario for “ABC” coming on as a new member of “XYZ” team assigned to work on a couple of components, the dossier might show (among other things):

Structure of the XYZ system around the parts ABC will work on;

Other members who (that) are working on places “nearby” or “related” to the XYZ system;

Anomalies ABC should be aware of (e.g., that there are no test cases associated with one of the components ABC would be working on);

Bug report trend recently or since the last release.

Adjacent lifecycle phases are those whose elements are directly related. For example:

Requirement phase and design phase are directly related and considered as being adjacent lifecycle phase because requirements from the requirement phase lead to designs in the design phase;

Design phase and coding phase are directly related and considered as being adjacent lifecycle phase because designs from the design phase lead to code in the coding phase.

Nonadjacent lifecycle phases are those whose elements are only related via the relationships of elements of intermediary adjacent lifecycle phases. For example:

Requirement phase and coding phase are considered to be nonadjacent life cycle phases because requirements from the requirement phase leads to designs in the design phase, which in turn, lead to code in the coding phase;

Intra-phase artifact relationships may also be used in relating elements from nonadjacent lifecycle phases. For example, “X” requirements phase is related to “Y” coding phase because:

1. X requirements phase developed requirement R1 requirements phase;

2. R1 requirements phase led to design D3 design phase;

3. D3 design phase led to the development of C5 coding phase; and

4. C5 coding phase was written by Y coding phase.

FIG. 1 illustrates a method of providing a list of elements (also referred to as an element dossier), for example, including those from nonadjacent lifecycle phases, related to a given target element in one embodiment of the present disclosure. A given target element may be a code, a phase in a life-cycle of code or project development, or the like. A target element may be provided by a user as a parameter or an input to a program module. Any other methodologies may be used to determine or select a given target element. At 102, a cross-lifecycle database may be obtained which includes relationships between elements from all lifecycles phases of interest. A cross-lifecycle database refers to database or data store that includes information related to projects and lifecycle phases of the projects. A cross-lifecycle database, for example, may exist in on one system or distributed across many systems. In one aspect, an automated computer module or software or the like executing on a processor may access and retrieve the relationships from the cross-lifecycle database. The relationships may be stored in a structured format readable by such computer module. At 104, the cross-lifecycle database is queried and a list of all those elements related to the given target element are retrieved. This may be performed by using the cross-lifecycle database's knowledge of the relationships between intermediary adjacent lifecycle phases, which may be stored as structured data in the database. Database may be queried and elements retrieved using an automated computer module or software or the like.

At 106, a tangible rendering may be provided. The tangible rendering can take many different forms, and this disclosure does not limit to any one rendering. Some examples of the rendering may include a display of the chains of related elements, e.g., textually, graphically and/or any other way. The tangible rendering, for example, may be a network with the nodes representing the elements and the links representing node-interrelationships.

An example of a chain is:

requirement_(—)12→design_(—)32→java_class_(—)13.

The examples here use java_class_(—)13 as a given target element.

The tangible rendering may also include a display of how a given element is related to its adjacent elements, e.g.:

requirement_(—)12→^(MOTIVATED)→design_(—)32→^(USED) ^(—) ^(AS BASIS) ^(—) ^(FOR)→java_class_(—)13.

The tangible rendering may also include an indication of whether the given elements preceded or followed the given target element chronologically (e.g., direction of arrow here indicates chronological order (earlier later), e.g.:

java_class_(—)13→application_(—)99→bug_report_(—)666

A selected symbol may be used to represent node interrelationships and indicate whether a given relationship occurred before (=>) or after (→) the target elements, e.g., in the case where java_class_(—)13 is the target element:

req_(—)12=>design_(—)32=>java_class_(—)13→app_(—)45→bug_report_(—)666

The tangible rendering can indicate Boolean combinations (i.e., two or more elements combined with a Boolean operator), e.g.:

OR(Bob, Carol, Ted, Alice)=>req_(—)12=>design_(—)32=>java_class_(—)13

AND(cost_req_(—)32, functional_req_(—)24)=>design_(—)32=>java_class_(—)13

A user may be given an option to restrict the elements to be retrieved. For example, the retrieving of elements may be based on a temporal factor, e.g., only show element created since a given date, show those elements that were created or edited by a given creator or editor, show only those elements that are in some way related to a particular element (e.g., “retrieve all bug reports that are in any way related to requirement_(—)36”). Other restrictions or selection factors may apply.

The lifecycle elements can include but are not limited to requirement documents, design documents, code, text, diagrams, tests, bug reports, users (e.g., employees, managers, customers, third parties (e.g., a software development firm)), multimedia, comments, beta-data annotations to other elements, analysis of other elements, hardware, services, hybrid compound objects (products), i.e., ones including both software and hardware, people, and roles. These elements may be accessed using hyperlinks, the Unified Modeling Language (UML) of software designs, the directory of test cases, computer-aided design and computer-aided manufacturing (CAD/CAM) renderings of hardware designs, video recordings (e.g., of test executions), audio recordings, footnotes or cross-references to text sections

In one aspect, the present disclosure also includes creating a cross-lifecycle database. A cross-lifecycle database may be created, for example, by obtaining all of the relevant elements, obtaining all relevant lifecycle phases, determining the lifecycle phase for each element, and determining the relationships between the elements, both elements of the same lifecycle phase and of adjacent lifecycle phases. The information for creating the cross-lifecycle database may be retrieved from previously stored or recorded project information or obtained from a user.

In another aspect, a new element may be added to the cross-lifecycle database, for example, by obtaining the new element, determining the element's lifecycle phase, and determining any and all intra-phase and inter-adjacent-phase relationships between the new element and existing elements. The element and and all of these relationships may be added into the cross-lifecycle database. The new element may have been dynamically added to the project.

Relationships and/or derived relationships may be added between elements of nonadjacent elements to the cross-lifecycle database, for example, whenever such relationships become known. For example, since requirement ABC leads to design XYZ, and design XYZ was used to write component PQR, requirement ABC is related to component PQR. The derived relationships may be also added between elements of adjacent lifecycle phases, or even a single phase, if the derivation includes elements from nonadjacent lifecycle phases. For example, X requirements phase is related to Y requirements phase because:

X requirements phase wrote requirement ABC requirements phase,

Requirement ABC requirements phase lead to design QWE design phase,

Design QWE design phase lead to code component PQR coding phase,

Component PQR coding phase caused bug FED testing phase,

Bug FED testing phase lead to new requirement HIJ requirements phase, and

HIJ requirements phase, was written by Y requirements phase.

The derived relationships may include those retrieved from the cross-lifecycle database during the retrieving step in FIG. 2. The derived relationships in one embodiment may be explicitly identified as be derived in the cross-lifecycle database (e.g., setting their “derived” column value or the like to TRUE). A given derived relationship's derivation (i.e., history or logic behind the derivation) may be associated with the given derived relationship, and the association may be stored in the cross-lifecycle database.

If there are conflicts between the existing derived relationship and new ones, for example, resulting from the addition of a new element, the conflicts may be resolved, for example, by identifying a conflict (e.g., determining that an existing derived relationship conflicts or contradicts a relationship determined with a newly added element, and deleting the given derived relationship from the cross-lifecycle database. The contradicting derived relationship may be a chain of derived relationships.

In yet another aspect, a given element may be deleted from the cross-lifecycle database, for example, by obtaining the given element to delete, determining the element's lifecycle phase, and determining any and all intra-phase and inter-adjacent-phase relationships between the to be deleted element and existing elements. The elements and all of these relationships from the cross-lifecycle database may be then deleted. If an element is to be deleted, all derived relationships that are fundamentally based on (i.e., relationships that could not be derived from other exiting relationships) one or more of the deleted relationships, may be determined and deleted from the cross-lifecycle database.

The cross-lifecycle database may have its data updated for those entries relevant to the query when the query is evaluated. The adding, deleting, and/or updating may be performed dynamically.

In another aspect, a user may be enabled to subscribe to a given query so that they are notified whenever new matches appear. For example, a user may post a given query (to cross-lifecycle database), indicating that they want dynamic updates. The cross-lifecycle database receives modification of its elements and associations. The cross-lifecycle database recalculates the results of the query and sends the subscribed user the latest result set. The user may be able to choose a query from a set provided by the cross-lifecycle database. The cross-lifecycle database may send subscribed users updates by RSS/Atom feeds. In addition, the cross-lifecycle database may maintain a history of the previous result set returned to the user, and only send a newly calculated result set if it differs from the previous set.

The method described above may be implemented as a computer program module to include a user interface that allows for user interactions, i.e., inputting values by the user for the computer program module to use and/or outputting values by the computer program module the user to observe. FIG. 2 illustrates example components of the system of the present disclosure in one embodiment. A computer module 202 may be stored in memory 204 and run or executed on a processor 206 having one or more central processing units and/or cores or the like. The computer module 202 may interact with a cross-lifecycle database 208, for example, as described above, perform its functions. A user interface module 210 may be a part of or separate from the computer module 202 and enables the interaction between the computer module 202 and a user.

As described above, a dossier is information based on one or more evolving lifecyle slices. FIG. 4 illustrates lifecycle slices created based on definite physical relationships among entities, which may be discovered with data, for example, in data sources. One or more data sources 402, for examples, databases, content management systems (CMSs), warehouses, and others, may include artifacts and actors and various associated information. This type of datasource-level information is generally static and slow-changing, and provides information on definite relationships among the artifacts and the actors, and ways to infer or deduce definite relationships. For instance, using the data store, it may be possible to discover artifact relationships, e.g., foo( ) calls bar( ), both foo( ) and bar( ) being artifacts, person A manages person B, etc.

FIG. 5 illustrates inferred relationships. Inferred relationships are generally rapidly changing and may be less-than-certain. Inferred relationships may be detected based on the similarities in characteristics or behaviors of artifacts and/or actors. For instance, if artifact 1 (e.g., a design of a project) and artifact 2 (e.g., code implementing a project) have similar names, it may be inferred that they are likely related. Inferred relationship information may be rapidly changing, for example, too fast to ask for human intervention upon each change. An assessor 502 (e.g., an automatic computer program) may be employed to discover inferred relationships. The confidence level for the actual existence of the inferred relationship may be expressed as probabilities. Human may use or filter the probabilities based on individual tolerance levels.

FIG. 6 illustrates correlation-based relationships. Correlation-based relationships are generally time and context sensitive potential associations. This type of relationships may be detected over time, generally based on temporal patterns. A temporal correlation monitor 602 may be employed to observe the behavior of artifacts to discover the correlation-based relationships. For example, it may be observed that 90% of the time when foo( ) is modified, bar( ) is also modified. Thus, it may be concluded that foo( ) and bar( ) have correlation-based relationships. However, correlations may or may not imply existence of relationships. For example, even if “90% of the time, when X looks at Y, X also looks at Z”, may only mean that X does not like to look at Y and needs a dose of humor after looking at Y by looking at Z. Thus, such correlation may not mean that Z is related to Y. Further, the presence of a correlation may not suggest a very specific type of relationship, unlike inferred relationship, where an assessor knows what type of relationship it is looking for. For instance, even if correlation-based relationship is discovered that “90% of the time when foo( ) is modified, bar( ) is also modified”, that relationship may not specifically tell what relationship foo( ) and bar( ) have to causes them to be modified simultaneously or substantially simultaneously. Confidence level grows with number of “correct” instances detected, and may be represented by a probability number or distribution.

Lifecycle slicing may be based on an area of concern and context knowledge, e.g., person, role, task, project, and others. A set of relevant static relationship types, inferred relationship types, and correlation types may be selected. These imply a set of expected elements that should be part of a well-formed lifecycle slice. Lifecycle slice may be computed based on these, identifying artifacts, people, events that are in the slice, and artifacts, people, events that are not in the slice but were expected for a well-formed slice.
